[ann] [objective-cl-announce] Objective-CL 0.2.1
by Matthias Benkard 07 Mar '08

07 Mar '08

Hi all, I have released Objective-CL 0.2.1. This release adds convenience and robustness to the previous one. * Quick Summary Super calls are supported. Bugs have been fixed. You may omit DEFINE-OBJECTIVE-C-GENERIC-FUNCTION calls. * What's New? ** Super Calls Up to now, there was no way of doing the equivalent of a message send to `super' as in Objective-C. This has changed. Just as with CALL-NEXT-METHOD for standard methods, you may now either call (SUPER) as-is or with the arguments you wish to pass to it. See the SUPER function in the reference manual for details. ** Implicit Definition of Objective-C Generic Functions DEFINE-OBJECTIVE-C-METHOD now takes care of defining a suitable OBJECTIVE-C-GENERIC-FUNCTION for you if you don't do so yourself. ** Bug Fixes Lots of little bugs are gone as well. Among others, returning values from Objective-C methods now works much more reliably, and Lisp wrapper objects don't just vanish when the GC runs as long as the corresponding foreign instance is still referenced by Objective-C code. I'm still wondering what to do on garbage-collected Objective-C runtimes. Have fun! ~ Matthias _______________________________________________ objective-cl-announce mailing list objective-cl-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/objective-cl-announce

[ann] [objective-cl-announce] Objective-CL 0.2.0
by Matthias Benkard 05 Mar '08

05 Mar '08

Hi all, Objective-CL 0.2.0 has been released. This release is a major milestone on the way to 1.0.0. * Quick summary We can now define Objective-C classes and methods without writing a single line of Objective-C code. The API may not be stable and there might be crashes, but living dangerously is half the fun, right? ;) * What's new? ** Method call syntax #.(enable-method-syntax) We now support Clozure CL's new method call syntax via reader macros. That means you can write: (let ((lock (#/new (find-objc-class 'ns-lock)))) (#/lock lock) (print (#/stringWithCString:encoding: (find-objc-class 'ns-string) "Hi there!" 0)) (#/unlock lock)) In fact, as the reader macro does no more than offer an alternate syntax for symbols, you can do things like using it with APPLY as well: (apply #'#/stringWithUTF8String: (find-objc-class 'ns-string) (list "Hi again.")) ** Class definition You can now define classes. For example, the following will define a subclass of NSObject called MLKMyClass, including a native slot called FOOS and a foreign slot (that is, an Objective-C ivar) called FOO-COUNT (fooCount on the Objective-C side): (define-objective-c-class ns::mlk-my-class (ns::ns-object) ((foos :initargs :foos) (foo-count :foreign-type :int))) Simple CFFI type specifiers are recognised by :FOREIGN-TYPE, but please note that complex types such as struct and union types are not yet supported. ** Method definition You can now define Objective-C methods from Lisp for your own classes. The following will define the Objective-C method -(int)foo:(int)bar:(id)stuff:(id)do:(NSNumber *) on MLKMyClass instances: (define-objective-c-generic-function #/foo:bar:stuff:do: (self y z a b)) (define-objective-c-method #/foo:bar:stuff:do: :int ((self ns::mlk-my-class) (y :int) z a (b ns::ns-number)) (format t "Hello! Z and A are ~A and~&~A, respectively. Have a nice day." z a) (+ y 20)) Usage example: OBJECTIVE-CL> (invoke (invoke (find-objc-class 'mlk-my-class) 'new) :foo 3 :bar "abc" :stuff 3 :do 33) Hello! Z and A are #<NS:GSC-BUFFER-STRING `abc' {8230318}> and #<NS:GS-CACHED-INT `3' {812C5D0}>, respectively. Have a nice day. 23 Note that, at present, you absolutely have to call DEFINE-OBJECTIVE-C-GENERIC-FUNCTION before defining methods, because otherwise you're going to get the wrong type of generic function. All modifiers of the standard method combination should be supported in principle, but it's unlikey they'll work as expected. This is planned for a future release. &REST and &KEY arguments are not supported. #.(disable-method-syntax) ** Struct wrappers When an Objective-C method returns a struct, it is now wrapped in a FOREIGN-STRUCT; likewise for unions. If you want to prevent its automatic deallocation, you need to set its FOREIGN-VALUE-LISP-MANAGED-P property to false. This change has been made because it would otherwise not be safe to discard return values of Objective-C methods, a safety which both Objective-C and Lisp programmers have come to expect. ** COLLECT-CLASSES The new function COLLECT-CLASSES may be used to make all classes known to the Objective-C runtime available as CLOS classes under the NS namespace. In an ideal world, we'd do this automatically at system load-time, but registering such a large number of classes along with their metaclasses takes a long time on some CL implementations (CMUCL, SBCL), so it's the user's decision whether to use FIND-OBJC-CLASS for each class or COLLECT-CLASSES once for now. If you try the release out, please tell me what works and what doesn't. If you can't even get it to compile, that is helpful information as well. Of course, above all, have lots of fun! ~ Matthias _______________________________________________ objective-cl-announce mailing list objective-cl-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/objective-cl-announce

[ann] [clouchdb-announce] Released version 0.0.9
by Peter Eddy 01 Mar '08

01 Mar '08

I've released version 0.0.9 of Clouchdb. This release includes proper support for complex keys in ad-hoc-view and invoke-view functions. It is now possible to use s-exprs as values for :key, :start-key and :end-key parameters. - Peter _______________________________________________ clouchdb-announce mailing list clouchdb-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/clouchdb-announce

[ann] [clfswm-announce] CLFSWM wiki opened
by Philippe Brochard 24 Feb '08

24 Feb '08

Hi all, I've set up a wiki about CLFSWM here: http://hocwp.free.fr/clfswm-wiki/ Feel free to enhance it, share your ideas or your feeling about clfswm. There is a page for free discution if you find it more convenient than the mailing list. PS: Also, the devel mailing list is the prefered way to discuss about CLFSWM in general. Have fun, Philippe -- Philippe Brochard <pbrochard(a)common-lisp.net> http://hocwp.free.fr _______________________________________________ clfswm-announce mailing list clfswm-announce(a)common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/clfswm-announce

[ann] [clfswm-announce] Let's go for the next CLFSWM version
by Philippe Brochard 24 Feb '08

24 Feb '08

Hi all, As I said in the last mail, I've done a lot of rework on CLFSWM to change its internal structure. Now the code is much simple and there is no more needs for the pager. If you look at the code and want to walk throw the group tree, don't crash your head on a recurcif algorithm. You can simply use the with-all-* macros. Here are some examples: -------------------------------------------------- ;; Walk throw all childs (with-all-childs (*root-group* child) (typecase child (xlib:window (print (xlib:wm-name child))) (group (print (group-number child))))) ;; Walk throw all groups (with-all-group (*root-group* group) (print (group-number group))) ;; Walk throw all windows (with-all-windows (*root-group* window) (print (wm-name xlib:window))) ;; Walk throw all childs - First form is applied on windows and the ;; second on groups (with-all-groups-windows (*root-group* child) (print (xlib:wm-name child)) (print (group-number child))) -------------------------------------------------- Also there is less keybinding, just press 'm' in the second mode to open a menu. All is not already there (like pack, resize, the mouse...) but I use this version already so there is nothing that prevent to have it in the CVS.

[ann] [clfswm-announce] Major update of clfswm
by Philippe Brochard 18 Feb '08

18 Feb '08

Hi all, After some exchange with Cyrille Thouvenin I started to rewrite some parts of clfswm. The main major change is that there is no more references to workspaces, all is a group. There is a root group and there childs. A child can be a group or an application window. Here is the old data structure: -------------------------------------------------- (defstruct workspace number group-list) (defstruct group x y width height window-list fullscreenp) (defparameter *workspace-list* nil) -------------------------------------------------- Here is the new one: -------------------------------------------------- (defclass group name number x y w h layout window gc child ...) -simplified- (defparameter *root-group* nil "Root of the root - ie the root group") (defparameter *current-root* nil "The current fullscreen maximized child") (defparameter *current-child* nil "The current child with the focus") -------------------------------------------------- Now using clfswm is like walking throw a tree of groups and windows. Here is the current keybinding to navigate throw this tree: Alt-Tab: circulate throw childs of *current-child* if it is a group. Alt-Left/Right: circulate throw brother childs (ie: this is like workspaces) Alt-Up: select the first child. Alt-Down: select the father of *current-child* Alt-Enter: Make the current selected child the current root (ie maximize it) Alt+Shift-Enter: Make the father of current root the current root (ie unmaximize the current child) There is no workspace but the same effect is obtened by circulating throw brothers childs. The advantages: - you can have workspace in any level. - there is no need for the pager: _you_are_in_the_pager_!!! You can find some screenshots here for a better idea: http://common-lisp.net/project/clfswm/temp/ Others changes are: * group/window coordinates are in float number between 0 (left) and 1 (right) so we can zoom them. Each group have its own window. * each group can have its own layout: no-layout: groups have there size, windows are maximized in the father group maximize-layout: groups and windows are maximized tile-layout: groups and windows are tiled tile-left/right/...: tile like in larswm/dwm... ... and so on - it's very easy to add a new layout. * a group is named so you can tell where you want to map a new window. * Each time a new window is created each group can do something with it (nothing, absorbe this window, copy this window, open a new group and map the window in it, open it in the group named toto... This is a more general process than the previous control-o (open next window in a new workspace)) * Chained key binding. Key binding are grouped by action and there is a little window to present possibles choices (there is no more a lot of keys to remember). * Currently I'm trying to have a different focus policy by groups (I don't know if I'll integrate this by default). Ouf, here it is :) It's a great change but the code is more simple (for example there is no more duplicated code with the second mode and the pager because there is no more pager :) I'll commited all this changes. So don't be too surprised by the new cvs content!
